Estimated reading time: 3 minutes
If you’ve seen the Baxi E133 fault code on your boiler, don’t worry—this is a common issue, especially when the weather gets cold. The E133 code means there’s a problem with your boiler’s gas supply or ignition, and it stops the boiler from working properly as a safety measure.
What Does the Baxi E133 Fault Code Mean?
The E133 code shows up when your boiler has trouble getting gas or lighting up. It’s a safety feature to prevent any damage or danger.
Common Causes of the Baxi E133 Error code
Here are the main reasons why this Baxi E133 fault code error might happen:
1.Gas Supply Issues:
If your boiler isn’t getting gas, it won’t ignite. This could happen if the gas is turned off or if there’s a problem with the gas line.
2.Faulty Gas Valve:
The gas valve controls the flow of gas. If it’s not working right, the boiler won’t get gas, causing the E133 error.
3.Frozen or Blocked Condensate Pipe:
In winter, the pipe that carries condensation can freeze or get blocked. This can stop the boiler and trigger the E133 error.
4.Faulty Ignition Components:
If parts that help the boiler ignite, like the ignition electrodes, are faulty, you might see the E133 error.
5.Pressure Problems:
If the gas pressure is too high or too low, the boiler might lock out and show the E133 error.
6.Air in the Gas Circuit:
After a while of not using the boiler, air might get into the gas line, making it hard for the boiler to light.
